There were times when I would take pictures and notice some purple or blue edges around my subjects. I didn’t have a clue what these were, much more how to get rid of them. When a friend pointed out that they were called ‘chromatic aberrations’, I got worried because it sounded serious like some sort of camera disease.

Chromatic aberration (commonly known as ‘purple fringing’ or ‘color fringing’) occurs when the lens fails to focus all the different wavelengths of light in a certain focal point.
